T0 at whom it may concern:

Be it known that LOTTO W. SIEBERT, of West Gardner, in the county ofWorcester and State of Massachusetts, have invented certain new anduseful Improvements in Go- Carts, of which the followingis aspecification.

This invention has for its object to provide simple and effective meansfor adjusting the hinged back and dasher of a go-cart and holding saidparts in their raised and depressed positions.

The invention consists in the improvements hereinafter described andclaimed.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a side elevation of a go-cart embodying myinvention, the back being raised and the dasher lowered. Fig. 2represents a side view showing the back lowered and the dasher raised.Fig. 3 represents a side elevation showing both the back and the dasherraised. Fig. 4 represents a rear elevation, on a larger scale, showingparts of the seat and back and of the adjusting and locking mechanism.Fig. 5 represents a section on line 5 5 of Fig. 4. Fig. 6 represents asection on line 6 6 of Fig. 4. Fig. 7 represents a View similar to Fig.5, showing the back-supporting strut in a different position. Figs. 8and 9 are views similar to a part of Fig. 5, showing the back-supportingstrut in difierent positions. Fig. 10 represents a section on line 10 10of Fig. 4.

The same reference characters indicate the same parts in all of thefigures.

In the drawings, a represents the seat or bottom of a go-cart body, 1)represents the back, which is hinged at c to the rear end of the seat,and d represents the dasher, which is hinged at e to the front end ofthe seat. These parts and the side portions of the body may be of anysuitable form and construction. The back is supported either in theraised position (shown in Figs. 1 and 3) or in the depressed position(shown in Fig. 2) by means of a strut f, journaled in a bearing g on theupper portion of the back, and a locking member 72, supported by abracket '6, which is affixed to and projects rearwardly from the seat.The locking member his pivoted to thebracket i by means of trunnions hon the ends of the locking member, said trunnions entering sockets inthe bracket, which is shown in Figs. 6 and 7 as having two side portionsbetween which the locking member is located. In the locking member isformed a sloth extending lengthwise of said member. The lower portion ofthe strut f is flattened and formed to slidein the slot- 72. when thestrut is turned to the position shown in Fig. 7. The flattened portionof the strut is provided with two pairs of notches f, arranged atdifferent heights, said notches being formed to engage the lockingmember when the strut is turned crosswise thereof, as shownin Fig. 6.The upper portion of the strutis cylindrical and is adapted to rotate inthe bearing 9 to cause the flattened portion to assume the positionsshown in Figs. 6 and 7. The said bearing has two contracted end portionsg g, fitting the cylindrical portion of the strut, and an enlargedcentral portion forming a casing or chamber 9 Fig. 5, in which islocated a collar f afiixed to the strut, said collar abutting againstthe contracted portions of the bearing and preventing endwise movementof the strut in the bearing. A helical spring j, surrounding the collarf has one end j engaged with an car on said collar, its other end 7'bearing on the casing. The tendency of said spring is to rotate thestrut in the direction indicated by the arrow in Fig. 7, thus causing itto normally assume the position shown in Fig. 6, in which position it isarrested against further rotation by stopshoulders 71 formed on thelocking member h. When the back is raised, the lower notches in thestrut are in position to engage the looking member, and when the back islowered the upper notches are in position to engage said member. Whenthe back is to be moved from one position to the other, the strut isturned to the position shown in Fig. 7 and is then free to slide in thelocking member, the spring turning the. strut into engagement with thelocking member when the desired notches f coincide therewith. Thepivotal connection between the locking member and the bracket o enablesthe locking member to conform to the various inclinations of the strut,as shown in Figs. 8 and 9, Fig. 8 showing the position of the strut whenthe back is raised and Fig. 9 when the back is depressed. The upper endof the strut is provided with a handle f by which it may be turnedagainst the force of the spring.

7c represent toggle-links, the outer ends of which are jointed, the oneto an ear on the dasher and the other to abracketm, projectingdownwardly from the front portion of the seat. When said linksarestraightened, as shown in Figs. 2 and 3, they support the dasher in araised position, and when they are thrown out of alinement the dasherfalls to the position shown in Fig. 1. I provide means whereby thetoggle-links may be straightened to raise the dasher either by thedepression of the back Z) or independently thereof. Said means comprisea lever n, pivoted at n to the rear bracket i, a rod 0, connecting thelever n with the toggle-link 71:, a collar 19, fitted to slide on thecylindrical portion of the strut f, (said portion being adapted to turnin the collar,) and a rod q, connecting the collar 13 with the lever 11.When the back is raised and the dasher lowered, as shown in' Fig. 1,.thecollar 19 is supported in contact with or in close proximity to thestrutbearing g, so that when the back is'swung downwardly said bearingwill force the collar p and rod q downwardly, thus moving the lever n,rod 0, and toggle-links 7a 7a to the positions shown in Fig. 2 andraising the dasher. When the parts are in this position, a toe 70 on thelower end of-the toggle-link 7c bears on the rod 0, which preventsfurther forward movement of the meeting ends of the links, and thuslocks the links in their dasher-supporting position. The back may now beraised without affecting the dasher, the bearing g being separated fromthe collar 10 by the upward movement of the back, as shown in Fig. 3.Hence the back and dasher may be held in their raised positionssimultaneously. The dasher may be lowered without lowering the back bymoving the rod 0 backwardly, and thus breaking the togglejoint. This maybe accomplished by a direct backward pull on the rod 0, which may haveits rear end 0 bent to form a hook or handle adapted to be engaged bythe foot or hand of the operator. The same result may be accomplished byan upward pull on the collar 10 or rod q, the collar being in eithercase raised to contact with the strut-bearing c, so that the nextdepression of the back will raise the dasher. The dasher may, however,be raised without depressing the back by a forward push on the rod 0 orby a downward push on the collarp or red g.

It is obvious that the depression of the collar 10 may be effected by acollar or enlargement on the strut instead of by the bearing 9. In otherwords, the bearing g may be con sidered as a shoulder or enlargementwhich moves with the strut to depress the collar when the back is beingdepressed.

I claim 1. A go-cart comprising a seat, a hinged back, a strut journaledin a bearing on the upper portion of the back, andhaving notchesarranged at diiferent heights, said strut being adapted to assumedifferent positions by partial rotative movements in said bearing, alocking member supported behind the seat and having a strut-receivingslot, said looking member being formed to engage a notched portion ofthe strut when the latter is in one of said positions, and to permit theendwise movement of the strut in the slot when the strut is in anotherposition, and a spring engaged with the strut and adapted to normallyhold it in engagement with said locking memher.

2. A go-cart comprising a seat, a hinged back, a spring-controlled strutrotatively connected with the back and provided with notches arranged atdifferent heights, and a locking device formed to engage notchedportions of the strut and having a slot in which the strut is movableendwise, said locking device being pivotally connected to a support onthe seat, so that it accommodates itself to varying inclinations of theback and strut.

3. A go-cart comprising a seat, a hinged back, a spring-controlled strutrotatively connected with the back and provided with notches arranged atdifferent heights, and a locking device formed to engage notchedportions of the strut and having a slot in which the strut is movableendwise, said locking device being pivotally connected to a support onthe seat and provided with stops which limit the rotation of the strutby its spring.

4:. A go-cart comprising a seat, a hinged back, a bearin g attached tothe upper portion of the back and having contracted ends and anintermediate enlargement, a strut journaled in said contracted ends andhaving notches located at different heights, and a collar located insaid enlargement, said collar abutting against the reduced ends of thehear ing and preventing endwise movement of the strut, a locking deviceformed to engage notched portions of the strut, and having a slot inwhich the strut is movable endwise.

5. A go-cart comprisingaseat, a bracket affixed to the seat andextending rearwardly therefrom, a locking member pivoted to said bracketand provided with a strut-receiving slot and with stop-shouldersadjacent to the slot, a hinged back, a strut journaled in a bearing onthe upper portion of the back and extending down wardly therefromthrough the slot in the locking member, said strut having notchesarranged at difierent heights and formed to engage the locking member,and a spring engaged with the strut and with its bearing and adapted tonormally hold the strut in engagement with the locking member.

6. A go-cart comprising a seat, a hinged back, a hinged dasher, a strutengaged with the back, a locking member supported behind the seat, saidstrut and locking member co operating in supporting the back indifferent positions, a bearing or enlargement affixed to and movablewith the strut, and dasher elevating and supporting mechanism comprisinga collar having a sliding connection with the strut and located belowsaid enlargement, so that it may be depressed by the latter, andconnections between said collar and the dasher, whereby the dasher maybe raised either by the depression of the back or independently thereof.

7. A go-cart comprising a seat, a hinged back, a back-supporting strutjournaled in a bearing on the upper portion of the back and extendingdownwardly therefrom, means supported by the seat for locking said strutand supporting the back in different positions, a hinged dasher,toggle-links jointed at their outer ends to the dasher and to a bracketaffixed to the seat and adapted when straightened to support the dasherin a raised position, and toggle-straightening devices including acollar slidingly connected with the strut below the strut-bearing andconnections between said collar and the toggle-links whereby when theback is depressed the strut-bearing or its specified equivalentdepresses the collar and causes the latter through said toggle-links andintermediate connections to raise the dasher, the sliding connectionbetween the strut and collar permitting the back to be raised withoutlowering the seat.

8. A go-cart comprising a seat, a hinged back, a hinged dasher, a rearbracket extending rearwardly from the rear portion of the seat, a frontbracket extending downwardly from the front portion of the seat, aspringcontrolled strut journaled in a bearing on the upper portion ofthe back and extending downwardly therefrom, a locking member pivotallyconnected with the rear bracket and adapted to lock the strut and backin difierent positions, toggle-links jointed at their outer ends to thedasher and front bracket respectively, a lever pivoted to the rearbracket, a collar fitted to slide on the strut below the strut-bearing,a rod connecting said lever with one of the toggle-links, and anotherrod connecting the lever with the collar.
